METHOD AND DEVICE FOR TRANSMITTING CONTROL INFORMATION IN WIRELESS COMMUNICATION SYSTEM

摘要

The present invention relates to a wireless communication system, and more specifically, to a method and a device for transmitting control information. The wireless communication system can support carrier aggregation (CA). The present invention provides a method for allowing a terminal to transmit control information to a base station in a wireless communication system, and the method comprises the steps of: receiving from said base station at least one physical downlink control channel (PDCCH) and one physical downlink shared channel (PDSCH) through at least one serving cell that is configured in said terminal; and transmitting to said base station first control information which has bundled at least a portion of the control information for said PDCCH reception or the PDSCH reception that is indicated by said PDCCHs, wherein said first control information is transmitted by using a physical uplink control channel (PUCCH) resource corresponding to a second control information according to a preset rule, and said second control information can be related to a PDCCH which was last detected by said terminal among said received PDCCHs.
